    <p>Useful if latitude or longitude vector has spaces, tabs, etc.
CAUTION - Assumes stripping those out and making it numeric will fix whatever problem there was
and end result is a valid set of numbers. Inf etc. are turned into NA values.
Empty zero length string is turned into NA without warning. NA is left as NA.
If anything other than empty or NA could not be interpreted as a number, it
returns NA for those and offers a warning.</p>
